"The hypothesis that the living and nonliving components of earth function
as a single system in such a way that the living component regulates and
maintains conditions so as to be suitable for life.
This system is regarded as a single living organism. Earth ~ 4.54 BYO."
In the words of Carl Sagan
"Preserve and cherish that Pale Blue Dot. The only home we've ever known."
"I hope my Landscape Photographs portray this principal to all who view and enjoy them." - Robert
